Maybe miles are shorter in magic.
Maybe hours are shorter.
Maybe all the acceleration is in the last second.
My question wasn’t on the acceleration; it was on the practicality of playing quidditch at such high speeds. If they aren’t utilizing the broom’s awesome speed then it kind of defeats the purpose of having such a fast racing broom. Unless there is another sport which is mamesh a flying race.
Maybe they can only sustain the acceleration for a short time like a fraction of a second?
Definitely not mashma that way. However, if you are correct it would explain why over the course of the match they are not actually flying that speedily.
